T 0 all whom it may cancer n:

Be it known that I, CONRAl) MILL-En, a citizen of the United Statesresiding at Casper, county of Natrona, and State of Wyo ming, haveinvented certain new and usei'ul skilled in the art to which it appertains to make and use the sa1ne,-reference being had;

to the accompanying drawings, and to the characters of" reference marked thereon, V I

10 which 1S provided with a crank, portion which form a part of thisspecification.

This inventionrelates to an attachment that can be applied to the front of an auto} 111010116 of ordinary construct on, and which can be used for the purpose of dchvering;

power toothjer machines or for hoisting.

It is theobjectof this invention to providea devicethatcan be cheaply made and easily installed on an automobile, and which will be So constructed that it can he used awinchior loading and unloading, or for pulhng the car out of a mud hole, andwhich canalso be employed to deliver power to a belt jdriven machine.

In order to more clearly describe my invention I shall have referenceto the :iccompanying drawing in which Fig.1 showsa top'jplan view of the front end 1 of" an automobile equipped with my attachment; Y

is a lront elevation olithe gear of an automobile or truce, and 2 represents the framework of the chassis. Secured to the end of crank shaft 3 is a co'upling nemher a which is held thereon by a pin 5, or other The front surface of memher 4 is provided with a diametrical slot 6 whichis adapted to cooperate with the projection 7 on the end of the slidable collar 8. Secured to the transverse bar 2'is abearing' 9, and rotatably mounted therein is; a shaft 11 on the outside of the frameIQ. and a collar. 8 slidably but non-rotatably mounted on'the inner end thereof. Collar 8 has an annular groove intermediate its ends and straddling" saidfinember is a U-shaped yoke member 13 whose legs 14 engage in the slot12'and have their'ends held together by jlneans of a bolt I 15. The closed end of the Ushaped member 13 has an upwardly projecting part 16;

ed to move the clutch members 6 and 7 into engagement. 1 A spring 22 isjconnected to the rod20 and to the framework 2,a nd' is so tensioned that itholds the clutchmembers apart. I Y

iilecured tothe side of the chassis is an air pump'iZZ-l which is held in place by suitable straps 24-. The piston rod extendsdi'rom the pump and has its lrontend connected toone end of hell crank lever 26, which is pivoted at 27 to the frame'Q. The other'end of bell crank lever 22ers connected to the crank 11 by means of a pitinan 28. When shaft 10 rotates, piston rod 25 will be reciprocated and the pump 28 Operated By;

means of a hose (not shown) connected to an outlet29 the compressed air may be 0011- ducted tothe tire valve for inflation. The

pump is preferably provided with means.

(not shown) for disconnecting it so that .it will notb-e operated except when it is desired to compress airforany' purposej Secured to the framework 'oifth'e' car by any suitable system 'of'bra'ces, such as 30. is a gear casing; 31. (Figs. 3 and 4) whichhas rotatably mounted therein a worm gear 32- Y which cooperatively engages with the worm light and 33 in such a manner that when the latter. is turned the gear 32 will be rotated. One end of worm 38 is provided with a socket 334: having a square openingdS adapted to receive the squared end of shaft 10.

The other end of the worm 33 has a square end 86 which is adapted toreceive a crank or to have mounted thereon a pulley of some kind. When the clutch members 6 and 7 are engaged, and the engine 1 operated, it is evidentthat shaft 10 will be turned and will rotate the worm 33, which will transmit the motion to the worm gear 32 and shaft 37. I provide shaft 37 with two projecting ends 38 and 39, which are square in cross section and adapted to receive the drum shown; in Fig. 5, or any of the pulleys or sprocket wheels illustrated. v b If it is desired to use my device as arwinch for hoisting heavy objects, the ,drum 40 shown in Fig. 5 may .be applied to either one of ends 38 or 39, and the cabled-1 extended to the place where it is to be employed, If it is desired to load material on the truck from the rear end the cable ll may be'run over pulley to be loaded. If theloading is to be done from the side, the rope ma be passed'over pulley 43 on the end of the swinging arm at of the upright post 45, and when. it is de sired to pull the truck out of themud, the. rope may be fastened to a stake or pin in the ground.

more, speed is required, the; drum may be secured to the end 36 in the manner shown in Fig. 2. .The belt pulley l6 (Fig.

7) can be secured to end 36 or to either one of ends 88 or 39. "For, the 'purpose of hoisting or. pulling, it may be desirable to employ a chain cable, and for the purpose of coopcrating therewith I have provided a special sprocket wheel at (Fig. 8) which is so designed that it will cooperate with the links in the chain. I

As the specific manner in which my attachment is secured to the machine is different for different machines, I have merely indicated the securing and bracing members in a general way, and I do not intend to convey the idea that the device shall be installed exactly as in the manner shown, but that such modifications may be madeas are necessary;

5 It is apparent from the above that have provided an attachment that can be readily installed on trucks and automobiles, and which will enable the operator to perform various useful operations which will be of great assistance in loading and unloading, and which will also enable him to pull the machine out of a mud hole or ditch by means of its own power.

I desire to call attention to the fact that 42 directly back to the object If the objects to be raised are tached to the ends 38 or 89, the winding drum cannot be rotated by the action of the load, as the screw 33 will hold the wheel 32: against turning, and the load can then be lowered slowly by means of a crank applied to the end 36.
